The VCNL4000 contains twelve 8 bit registers for operation control, parameter setup and result buffering. All registers are
accessible via I

Device Address
The VCNL4000 has a fix slave address for the host
programming and accessing selection. The predefined 7 bit
I
significant bit (LSB) defines read or write mode. Accordingly
the bus address is set to 0010 011x = 26h for write, 27h for
read.
REGISTER FUNCTIONS
Register #0 Command Register
Register address = 80h
The register #0 is for starting ambient light or proximity measurements. This register contains 2 flag bits for data ready indication.
With setting bit 3 and bit 4 at the same write command, a simultaneously measurement of ambient light and proximity is done.
